Elmers grasshopper

[Mbergmueller]

I've almost completed Elmers Grasshopper engine. I drew the plans(slightly modified) into D2NC then imported it to Mach 3. I've CNC'd my mini mill using the stock screws with split nuts. The mill works..OK. I have to re-tighten things every once and a while.
But the engine is running an looks good. I still have some finishing work and polish to do. Here is some pics and video

Very nice and runs very well as the slow speed indicates. Thanks for sharing the pics and vids.

Thanks guys, the big flywheel(almost too big) helps. It's still taking a lot of pressure which I hope will come down with running. I might thin the flywheel casting also.

Very impressive Mbergmueller! Thm:

When they will run that slow you got it ALL right.
Well done!
